1) Verify a-(-b) = a + b for the following values of ‘a’ and ‘b’.

(a)

(b)

(c)

a = 75,

a = 118,

a= 25,

b = 84

b = 125

b = 30

2) Write down a pair of integers whose

(a) Sum is – 3

(b) Sum is 0

(c) Difference is 2

(d)

Difference is – 5

3) Verify the following:

a) (-21) ×[(-4) + (−6)] = [(-21) × (-4)] + [(−21) × (−6)]

b) 15 x [6+ (-3)] = [15 x 6] + [15 x .

c) (-15) x[(-8) + (−6)] = -15) x (-8)] + [(-15) × (-6)]

4) Evaluate :

a) (-100) + 5

b) (-36)

c) (-41) [(-40) + (-1)]

d) 0+ (-18)

e) [(-36) 12] + 3

f) (-50) + (50)

g) 60 ÷ (-6)

h) (-48) – 48

Step-by-step explanation:(a) , 27+(-30)= -3

(b) , 2+(-2) = 0

(c ) 80-78 = 2

(d) 45 – 50 = -5

hope it helps
